These films were made in different ratios of precursor gas[C6H6 ,HMDS(C6H18Si2NH) and HMDSO(C6H18Si2O)] and deposition time(30min,60min,and 90min).The experimental results are as follows: films which use C6H6 as its precursor gas contain most sp2 bondings of carbon,as a result, have the lowest transmittance of visual light(the average transmittance is about 10% in deposition time of 90min); films which use HMDS as its precursor gas contain least sp2 bondings of carbon,as a result, have the highest transmittance(the average transmittance is about 60% in deposition time of 90min). Films which use C6H6 as its precursor gas have the smallest relative optical gap[the average value is about 1.0 (e.v.)],and films which use HMDS as its precursor gas have the largest relative optical gap[the average value is about 2.1 (e.v.)].Films which use HMDS,HMDSO,and HMDS+HMDSO respectively as its precursor gas have both its relative optical gap and sp3 bondings of carbon increased as deposition time increases.
